To afl whom it mag concern.

Be it known that I, JOHN EMERY HARRI- MAN, J r., of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Edge-Setting Machines, of which the following is a specification.

u This invention relates to machines for setting or burnishing the sole edges of boots and shoes.

It has for its object to combine in a single machine the means for applying the preliminary dressingor dressings to the sole edge and a tool or tools for setting the edges, together with provisions for drying the dressing where the same is a liquid, and means for enabling the shoe to be held and shifted from one position to another so tha-t it may receivethe dressing and be subjected to the action of the settin tool without requiring intermediate han ing.

- A further object is to. provide holding against the setting tool or tools with Suficient force for the purpose desired, and

without requiring much expenditure of energy on the part of the operator. In

other words it has hitherto been necessary for wormen operating edge-setting machines to exert. a comparatlvely great upward pressure while, holding the sole edge.

of a shoe against the setting tool in order that satisfactory work may be done, and this has alwaysbeen considered as one of the most-laborious and strength taxing operations in the entire shoe factory, so that only very'strong men are able' to perform it, and even such men are unable to continue at such work for any great length of time.

' Accordingly, in carrying out the other objects of my invention, 'I have, provided a holder for the shoe which is so weighted or,

acted upon by spring or other pressure, that it more than counterebalances the weight of the shoe, and [exerts pressure thereon.

In this connection it been my object.

toprovide a holder which will accomplish suchf -result and also serve to carry the shoe directly from the positions in which it receives-tone or more coatings of a dressing or 'tion into eflect. the machine as seen from the right of Fig.

a resultant upward .burnishing tool.

vide a tank or tanks 12, 13, which are con-' of different dressings into the position where it is acted upon by the edge-setting tool.

In the accompanyin drawings, Figure 1 shows. an elevation o a machine embodying the principles of my invention in which is shown one mode of carrying the inven- Fig. 2is a side elevation of 1. Fig. 8 is a plan View of the machine.

. Fig. 4 is an elevation of the shoe-holding device or support as seen from the right of e Fig. 1, showing, diametrically difl'erent positions which may be given 'to a shoe held thereby. Fig. 5 is a sectional view and Fig. 6 an elevation of a form of applying dressing to the edge of a shoe sole adapted to be used-in connection with this machine. The same reference characters indicate the same parts in all the figures.

Referring to the drawings the reference numeral 1 represents the column of an edge-setting machine rising from a base or pedestal 2. "On the upper part of the column is an-edge-setti'ng tool 3, which may be of any suitable character and is preferably any one of the edge-setting or burnishing tools at present in common use. For the pu ose .of illustration I have shown the too as being'a blockcarried by areciprocat ing holder 4:, which is pivoted to a bracket '5, although it is to beunderstood that any other type of tool suitable for the purpose -may be employed. In the embodiment shown, the bracket '5 hangs from a table 6,

secured upon the top of the machine and the setting tool holder is oscillated by a lever 7 connected by a link 8 with a crank stud 9011a shaft 10 which is journaled in a bearing 11, rising from theitable 6. 'Iwo. or more tools? and 3" respectively may be .mounted upon the holder-Q4: in interchangeable relation so that either may beused or acting on .diflerent' parts of the sole, such as the fore part ofthe sole and the shank respectively.

One of the principal objects ofmy invention, as before stated, isto provide means for applying dressings such as gum, ink,

blacking or other dressing to the edge of the 1 Sole before the same isacted upon by the For this purpose'I proveniently supported upon brackets 14= above nishing tool, I find it convenient to supply a tank 12 with gum, and a tank 13 with the blacking' or other dressing, and to arran e the outlet pipes 15 and 16 as shown best in Fig. 3, so that a shoe may be held in position to receive gum issuing from the nozzle of the pipe 15, and then be inked by the dressing issuing from the nozzle of the pipe 16 in succession before being presented to the setting tool.

' In order thatthe dresslngs may be applied with someforce and fully distributed,

and in order further to dry the dressings where the same are in liquid form, I find it convenient to blow the dressings in an atomized condition against the sole edge by compressed air which may be heated if desired to securemore rapid drying, and further to direct an additional current of air, heated if desired, upon thesole, so thatit blows against the dressing as soon as it is applied and dries the same almost instantly. For

this purpose I provide a compressed air tank 17 which is placed at any. desired point and may conveniently be mounted beside the dressing tanks upon brackets 18. A pipe. 19 issues from the air tank and has branches 20 and 21 extending to the outlet pipes of the dressing tanks respectively, while from each of these branches extend pipes 22, 23 andn24, 25 respectively. The pipes 22, 24 lie beside the outlet pipe5.15 d 1 of the dressing.

tanks respectively and blow the dressing therefrom'in a finely divided condition with an action similar to that of the ordinary well know'n'atomizer. The other pipes 23' and 25 respectively are provided for directing a stream of air upon the edge of the sole after the dressing has been applied thereto, in order to dry the same.

The shoe is supported by a device which is capable of movement so that the edge of the sole of the shoe may be presented successively to each of the various instrumentalities which act upon it, that is, to the outlets for the dressing and to the burnishing tool, and also with provisions for moving the shoe while adj acentto any one of these 'instrumentalities so that the entire extent of its sole edge is presented thereto. The holder therefore forms an important element of my invention in combination with the machine as a whole. A suitable embodiment of the holder is the one here illustrated which consists of a rod or bar 26 having a of different sizes. parts and adjustment are such that when.

pocket or saddle 27 to receive the shoe and mounted for universal movement. That is, the rod is mounted so that the shoe-holding portion thereof may be raised or lowered, moved laterally to one side or the other, moved in or out, and rotated about its axis. To permit of these motions it is supported by a bracket 28 projecting from the column 1 and having an aperture through which the rod extends. This aperture is a suflicient amount greater in diameter than the rod to permit of lateral and vertical movement of the rod to the desired extent, and on the rod on each side of the bracket are mounted collars 29 and springs 30, which latter act against fixed abutment shoulders 31 on the rod. The action of these springs is to tend to hold the rod in a position of equilibrium wherein it extends perpendicular to the bracket 28, while at the same time permitting the desired swing of the rod to take place, and also permitting the rod to be moved endwise. Any other form of universal connection between the rod and the supporting bracket might be employed, but

- of theshoe to embrace the fore part of the latter and assist in holding it in place. The holder also has a bracket 33 secured to the rod and projecting in such a position .that

the sole of the shoe may rest against it, leaving the edges of the sole exposed between the bracket and the sprin arms 32. After beingplaced in the hol er the shoe is secured by clamping means such as that shown in Figs. 1 and 4, consisting of an angular bar 341 against which the tread surface of the heel is adapted to bear, and the end of which is carried across the rest of the heel and provided with a lip 35 which may be formed with teeth or a serration as shown in Fig. 4. This angular bar serves as a clamp which is forced against the breast of the heel by a cam lever 36 having a handle 37. The clamp is engaged with a block 38 adjustably mounted upon the cam lever and controlled by adjusting screws or bolts 39 by which it may be regulated to shoe heels The proportions of the the clamp is tightly held against the breast of the heel by the cam lever, the handle 37 of the latter extends downward from the holder. A second handle 40 extends out- 0' expelled. The longitudinal movement of ace-eta eration'is an extremely laboriousand trying one for the operator, as it involves pressing the shoe upward with great force against the setting tool. One of my objects has been therefore to make the shoe holder with pro- Visions for exerting an upward pressure on the shoe to relieve the operator of this exceedingly difficult and trying work. For this purpose I arrange the rod 26 so that it extends a considerable distance beyond the supporting bracket 28 and provide means for exerting a sufliciently powerful downward pressure on this pro ecting end to overbalance the weight. of the shoe and holder and to exert sufiicient upward pressure on r the latter to relieve the operator of the necessity of using his own strength to any great degree for the purpose of-pressi ng the sole edge against the setting iron. This means may be a weight 41 or spring 42 or both as here shown. j This weight maybe at tached to the rod in any'convenient way such as by screwing it upon the threaded ex-1 tremity of the rod as here shown. The rod also has an' angular arm 43 extending downward, to which a weight 44 is connected in the same manner, and'also a spring 45 if desired. This weight supplements the weight 41 in pressing the shoe upwardly and also tends to hold the latter in a vertical position with its toe pointing upward, thus assisting the operator when the side edges of the sole are presented to the setting tools.

In operating the machine the shoe holder is first swung into the position illustratedin the drawings when the edge of the shoe sole is presented to the outlet nozzle of the pipe 15,-from which a dressing such as a gum is the shoe holder-permits the latter to be shifted from the position. it occupies when the shoe is applied thereto into the position for presentin the shoe to the nozzle. The handles 3 and 40 being grasped, the holderis oscillated about its own axis and at the same time raised and lowered to the extent necessaryforfcarrying the entire extent of the sole edge past-the nozzle to receive the dressing. Thisdr'essing is evenly distributed over the entire edge-and is immediately or quickly dried by the air issuing from the tube '23. The dressing is prevented from flowing over andsoiling the bottom of theshoe sole or the upper leather by guards 46 and 47 which flank the nozzle of the pipe15 and are separated by a width just suficient toradmit the shoe sole. These guards are preferably flexibly or yieldingly mounted so as to admit the sole edges between them, and,

to. embrace such 'edges closely. .After the first dressing has been appliedto the shoe, the holder is swung radially in a path indicated by the line of arrows in Fig. 3, until the'shoe is presented to the setting tool and the first dressing is set, then the shoe is carried back to the nozzle of the outlet pipe 16",

from which ink, blacln'ng or other dressing issues. This dressing is. also forced out by a jet of air from the pipe 24 and is dried by air issued from the pipe 25. The nozzle of this pipe as well as of the other is provided with guards 46 and '47. an auxiliary v drying means ll provide a, nozzle 48 extending along the sole rest 33-of the holder, and having a number of apertures through which air heatedif desired, is blown against the sole near the edges thereof. This nozzle is fed by apipe 49 which is carried along the rod 26 of the shoe holder and is connected in any desired way with the-air tank 17. The shoe holder is finally swung so as to present the edge of the sole to the action of the burnishing tools 3 or 3 fora final setting, and as before the holder'is rotated about its own axis and at the same time moved laterally and vertically to present the entire extent, of the sole edge tothe tools. In this operation, as also in the gumming and inking stages, the weights orsprings hold the shoe upwardly with considerableforoe and relieve the operator of any eflort other than tllat necessary for swinging and-turning the s oe.

Mention has beenmade of the fact that the air for applying and dryingthe dressing may be heated. Means for thus heating the air is illustrated inlFig. 2 which consists.

of a gas jet 50 from which a flame issues he neath the air tanklTand theoutlet thereor pipe 20 als'ohas a valve 55 havin an opcrating arm 56. connected by a lin 57 of the treadle 58 beside the treadl'e 54. These treadles are placed close together so that if desired they may be depressed by the foot Y of the operator atone and thesame time, or they may be separately depressed. 'While the shoe is held nearthe nozzle of the pipe V 15, either or both of these treadles are depressed and the dressing or air orf'both are permitted to flow against the edge of the sole. Likewise the outlet pipe 16 and the air. pipe 21 have valves 59 and '60 ,respec ar-u:

Here the applying means is a circular brush 67 mounted to revolve about a tube 68 which leads from the tank of dressing. On the hub of the brush is mounted an air turbine 69 which is rotated by a blast ofair issuing from the pipe 70 which leads from the air tank 17. The dressing issues from the pipe 68 through a line of orifices 71, either under its own head, or under pressure of air introduced either into the tank of the dressing, or into the pipe 68. The centrifugal action of the brush and the force of the air throw the dressing outward and the brush applies it to the edge-of the sole. The brush is entirely surrounded by a casing 72 which has an opening suflicient to admit the edge of the sole. The casing on one side of the opening serves as a shield to prevent the dressing from flowing on the upper leather of the shoe and a second shield 73 is applied to prevent the dressing from flowing over the bottom of the sole. The air, after driving the turbine issues from the exhaust 74, which 1s so arranged as to direct the air against the edge of the sole for the purpose of dry- 1 ing the dressing.

4 to place the shoe in a rack to dry and then This invention is ameans of efiecting a comparatively great saving in the cost of shoe-making, as it enables the whole process of treating the edges of the shoe soles, including the applying of difi'erent dressings thereto and burnishing the edges to be completed in a single operation. It has hitherto been the practice to apply first a gum to the sole edges by hand by means of a brush,

set the edges bypresenting. the shoe to an edge-setting machine,.after which one or more coatings of inkor other dressing are app-lied to the sole also by hand, and such coat or coatsmust be permitted to dry before the shoe is presented to the edge setter fdi' the final setting operation. This involves'four separate handlings of the shoe and at least two drying periods with a corresponding loss of time, and the services of two employees, t0 wit., an operator of the edge-setting machine and a helper, who is usually a-boy, and whose duty it is to apply the gum and blacking or other dressing to the sole edges and place the shoes upon a rack where the dressing. may dry and' from which, the shoes may be taken by the operator of the machine.- That is, each setting machine requires the services of two operatives and the shoes have to, be handled first by the helper who applies the gum, second by the setter who operates the edge-setting machine and burnishes the gum into the edge of the sole, third by the helper, who next takes the shoe and applies the blacking or other dressing, and fourth by the operator of the setting machine who gives the sole edge the final set. If additional coats of dressing are applied the shoe must be handled a correspondingly greater number of times, each followed by the necessary period for drying. Incidentally it involves also the danger of injuring the shoe by careless applying of the dressing, in which the dressing may be smeared over the upper leather or the bottom of the sole, or may run thereover or drip upon shoes placed in the lower part of the rack in case an excess of the dressing is applied. There is danger also of the operators soiling the shoes by handling them when their hands are wet with the dressing. Many shoes are either entirely spoiled or their value reduced by the carelessness in applying the dressing, or handling them, by virtue of which the uppers become smeared with the gum or other dressing. -This causes otherwise high grade shoes to become unsalable at their proper price and to be classified in inferior grades.

By my invention all dan er of spoiling a shoe by improper application ofdressing is eliminated and these several operations involved in finishing the sole edges are com menced and completed in a single continuous act of one operator, without rehandling, and without loss oftime in allowing the dressing to dry. This is due to the fact that the dressing is dried immediately after its application. Also the labor 'cost is reduced, because one operator can attend to the entire treatment of the sole edges in but little more than the time required for the setting or burnishing of the ed es. The operator of the edge-setting mac line while handling the shoe but once can present the shoe in turn to the gumming device, the setting tool, the inking device, and the setting tool again, and this asmany times as may be required-to give the desired finish to the edge of the'sole. The drying of the dressings is effected immediately by the means provided for that purpose as hereinbefore described and thus the element of time lost while waiting for the dressings to dry is eliminated. At the same time the danger of spoiling shoes by careless application of the dressing and smearing the same or allowing it to drip on'the upper leather is avoided on account of the character of the dressing-applying means before described. The cost of the edge-setting part of the manufacture of a shoe is thereby materially decreased by saving the wages of the assistant and the time of the setter, while the loss due to spoiling the shoes by dressing smeared over the upper leather is wholly saved. In passing it may be noted that the dressings which are ascents indelible as possible, so that as-a result it is almostimpossible-and in some cases it is absolutely impossible to remove stains caused by applying these dressingsto the upper leather. At the same time the work is made lighter and less'injurious for the operator on account of the aid which is given by the shoe-holder in pressing the edges of the sole against the setting tool.

All the elements of the combination are contained in the single united machlne, including the tanks for the air and dressing and the setting tool, which are mounted upon' the. top of the machine, and the driving apparatus for both'driving the tool and compressing the air which is contained in the pedestal of the machine. The means for driving the burnishing tool is a belt 7 which passes over a pulley 7.6 uponthe' shaft 10 and is driven b a pulley 7 7 on a countershaft 78, mounte is driven by a belt 7.9. This counter-shaft in the pedestal 2 which also serves to compress the air, as it carries a crank pin 80 which operates the piston of an air pump 81. The latter discharges into a reserpoir 82, from which the air is conducted the tank 17 by a pipe 83.
